Abstract

In this study, the transient behavior of a three-phase distribution transformer under fault and reclosing conditions is investigated using Ansys Maxwell and Twin Builder environments. The transformer is first modeled in Maxwell 3D considering realistic geometric and material parameters. The electromagnetic parameters such as winding resistance, leakage inductance, and magnetizing inductance are extracted and transferred to Twin Builder for time-domain simulation. Fault scenarios, including phase-to-ground circuits is introduced to evaluate the impact of sudden disturbances on the transformer’s electrical characteristics. Subsequently, an automatic reclosing operation is implemented to restore the system after fault clearance. The transient waveforms of voltage and current before, during, and after reclosing are analyzed to observe the resulting overvoltages, inrush currents, and oscillations. The results demonstrate that the reclosing process significantly affects the post-fault recovery period and may induce temporary magnetic saturation or current asymmetry depending on the fault type and reclosing timing. This integrated modeling approach provides a practical framework for studying fault recovery mechanisms in power transformers and contributes to improving the reliability of power systems.
